Anticoagulation and Bleeding: A Pooled Analysis of Lung Cancer Trials of the NCIC Clinical Trials Group

BACKGROUND: Patients with cancer, including lung cancer are at an increased risk for venous thromboembolism and frequently are anticoagulated. Due to concerns of bleeding and drug-drug interactions, many clinical trials suggest the use of low-molecular-weight heparin (LMWH) rather than warfarin (coumadin) for patients requiring anticoagulation. We sought to evaluate, in a retrospective analysis, whether these recommendations were appropriate.
